BOOL scrolling;///是否正在上拉刷新

_refreshControl =

_refreshControl.tintColor = [UIColorcolorWithHexString:@"#AAAAAA"alpha:1.0f];

[_refreshControladdTarget:selfaction:@selector(requestNewData)
forControlEvents:UIControlEventValueChanged];

self.refreshControl =
_refreshControl;

///添加表格底部的Actitivy;

self.activity=
[[UIActivityIndicatorViewalloc]

initWithFrame : CGRectMake(0, 0,
32.0f, 32.0f)] ;

[_activitysetActivityIndicatorViewStyle:

_activity.color=[UIColorblackColor];

[self.tableViewaddSubview:_activity];

viewDidLoad 里面：

///下拉方法。
